I shouldn't have to use any of those companies. Shock absorbers are not a restricted import. I've imported four pairs of motorcycle shocks and an upmarket set of shocks for my Jeepster with no problems from US or Australian customs or up until now, eBay's Global Shipping. I got this email from them today. It's an eBay Global Shipping Program rule apparently...You learn something every day. I'll make sure the sellers don't ship shocks via eBay Global in the future.
Dear firko,
We apologize that you were not able to receive item#:121227274958 . This item was sent through the Global Shipping Program and could not be delivered to you because the shipment was a restricted item for import through the eBay Global Shipping Program. It may be possible for you to purchase these items on eBay from the United States if the seller is willing to send the item to you directly but, they won't be able to be shipped through the Global Shipping Program. The program has restrictions with any type of air, gas or liquid in a compressed container and all shocks are being restricted through the program.
